Abstract

From thirteenth international conferencc on thermal conductivity; Lake Ozark, Missouri, USA (5 Nov 1973). A longitudinal heat flow technique for precise measurement of thermal conductivity, electrical resistivity, and Seebeck coefficient over the temperature range from 80 to 4OO deg K is described. The basis of the technique is the use of a calibrated platinum resistance thermometer to provide in-situ calibrations of specimen thermocouples. The total determinate errors at 273 deg K are plus or minus 0.23% for electrical resistivity, plus or minus 0.49% for thermal conductivity, and plus or minus 0.07 mu v/K for the Seebeck coefficient when Pt wire is used as the reference. Experlmental results on two high-puriiy molybdenum specimens with cross-sectional areas differing by a factor of four are presented to demonstrate the system precision and low level of indeterminate errors.

Thermal conductivity, electrical resistivity, and Seebeck coefficient of high-purity chromium from 280 to 1000 K

Journal Article Moore, J; Williams, R; Graves, R - J. Appl. Phys.; (United States)

The thermal conductivity lambda, electrical resistivity rho, and Seebeck coefficient S of a high-purity Cr specimen (rho/sub 273//rho/sub 4.2/ = 380) were measured from 285 to 1000 K. The rho and S of two other Cr specimens (rho/sub 273//rho/sub 4.1/ = 380 and 58) were determined from 300 to 1300 K. The rho and S results from the three specimens are in excellent agreement, and all three properties agree to within experimental uncertainty with previous low-temperature results on the same specimens over the temperature range of overlap. Near T'/sub N/ (300--320 K), the present lambda results are within 0.7% ofmore »« less

Computer-operated quartz differential dilatometer

Conference Kollie, T; McElroy, D; Hutton, J; ...

From international symposium on thermal expansion of solids; Lake of the Czarks, Missouri, USA (7 Nov 1973). A quartz differential dilatometer was interfaced with a Digital Equipment Corporation PDP-8 computer to automatically measure the thermal expansion of solids from 300 to 1000 K. A Carson-Dice Electronic-Mechanicai Micrometer, readable to 2.5 x 10/sup -6/ cm, was employed for length-change measurements accurate to 2.5 x 10/sup -5/ cm. Calibrated Pt/Pt/ sub 90/Rh/sub 10/ thermocouples were used to measure temperature changes to plus or minus 0.22 K. The software and hardware necessary to completely automate the measurements are described. Measurements on National Bureaumore »« less

A LOW TEMPERATURE ADIABATIC CALORIMETER FOR CONDENSED SUBSTANCES. THERMODYNAMIC PROPERTIES OF ARGON

Journal Article Flubacher, P; Leadbetter, A; Morrison, J - Proc. Phys. Soc. (London)

An adiabatic calorimeter was constructed to study properties of condensed substances 2 to 300 deg K. Two resistance thermometers were used, one of platinum for T > 11 deg K, and one of carbon for T < 11 deg K. The carbon thermometer was calibrated on the thermodynamic temperature scale by using the calorimeter vessel as a gas thermometer; subsequent absolute shifts of its resistance on cycling between room temperature and liquid helium temperatures were taken into account by calibrations against the platinum thermometer. Heat capacities of solid and liquid argon were measured between 2 and 86 deg K withmore »« less

Thermal conductivities, electrical resistivities, and Seebeck coefficients of YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} superconductors from 80 to 300 K

Technical Report Yarbrough, D; Williams, R; Shockley, D

Thermal conductivities, electrical resistivities, and Seebeck coefficients of three polycrystalline YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} specimens have been measured over the temperature range 80 to 300 K in a longitudinal-heat-flow apparatus. Smoothed values for thermal conductivity, and electrical resistivity have been obtained for temperatures above the superconducting transition temperature of 90 K. The thermal conductivity values decreased as the temperature was increased, a trend which is inconsistent with the results of some other investigators. The thermal conductivities were less than previously published values and it is suggested that these differences are due to radiative heat loss in the published values. Thismore »« less

Thermal conductivity, electrical resistivity and Seebeck coefficient of high purity iron and selected iron alloys from 90 K to 400 K

Technical Report Holder, T

The thermal conductivity, electrical resistivity, and Seebeck coefficient of high purity iron, two iron-chromium alloys, one iron-nickel alloy, and one iron-chromium-nickel alloy were measured over the temperature range from 90 K to 400 K. Smoothed values for the thermal conductivity and electrical resistivity were used to calculate the electronic thermal conductivity, the lattice conductivity, and the Lorenz function by means of a binary alloy separation technique. The lattice conductivity and Lorenz function exhibited little change due to the addition of chromium; however, the addition of small amounts of nickel resulted in significant property changes. The lattice conductivity at high temperaturesmore »« less
